As a good embodiment, described USB controller can be USB OTG(On-The-Go) controller, it can be chosen as host mode or slave mode according to the difference of connection device.
When system powers on, USB controller, according to the equipment that is connected to ANTENN AUDIO adapter, judges that the equipment connecting is usb host or USB slave; USB slave if, ANTENN AUDIO adapter arrangement is from as USB Audio pattern, is USB flash disk pattern below other situations.Concrete grammar is as follows: when system powers on, USB controller arranges oneself for host mode, waits for the connection of audio-frequence player device, if audio-frequence player device can connect, audio-frequence player device is slave mode, and ANTENN AUDIO adapter arranges oneself for USB Audio pattern; Wait for certain hour, if audio frequency apparatus does not have to connect, USB is transformed into slave mode, and adapter arranges oneself for USB flash disk pattern.
After system powers on, wireless identification unit reads wireless phy interface data, obtains type and the model of wireless PHY unit 201, and wireless identification unit sends to agreement loading unit the categorical data of the model getting.Agreement loading unit loads corresponding protocol-driven in protocol processing unit according to type and model in storer.
After agreement has loaded, protocol processing unit is communicated by letter with wireless host device by the wireless PHY of wireless phy interface control unit, obtains the audio data file form of wireless transmission.Protocol processing unit sends to audio driven loading unit audio data file form, and audio driven loading unit loads corresponding audio decoder and is driven in audio decoder.
Be divided into USB flash disk pattern below and USB Audio pattern is described respectively:
One, USB flash disk pattern if:
As shown in Figure 4, after system powers on, file system simulator reads the audio compressed files of supporting in audio driven loading unit and supports form kind, simulates respectively the file of each audio format file.File is organized with file system format, file system format comprises the conventional forms of audio system such as FAT12/16, FAT32, NTFS, the size of each simulation files is the maximum size that current file system is supported, if want to realize Play Control, each class file number is at least wanted 3 files.
When ANTENN AUDIO adapter is inserted into after audio-frequence player device, audio-frequence player device is by the content in USB interface access file system, and file system simulator judges by judging its access file type the audio data format that audio-frequence player device is supported.File system simulator sends to audio driven loading unit the audio data format judging, and in audio driven loading unit read memory, the coding of respective audio form drives, and is loaded in audio coder.
During equipment work, wireless phy interface obtains wireless data, send to protocol processing unit to isolate voice data, voice data formed PCM(Pulse-Code Modulation after entering audio decoder, pulse code modulation (PCM)) data, PCM data are being issued audio coder, form the audio file formats data that audio player can be identified, data send to file system simulator again, when audio-frequence player device reads usb data, just transmit audio coder and send to the data of file system simulator to USB controller.
It should be noted that, above-mentioned audio file formats can be: the proprietary data format that other known audio file formats such as wav form, mp3 form, wma form, acc form, flac form and wireless receiving and dispatching two ends consult.
File system simulator is by judging whether visit data judges the state of audio player in suspending and playing to USB controller.If file system simulates 3 same formatted files, by judging that the order of access file judges the selection of audio player to played file, such as access file 1 before, the file 2 of access now, be judged as audio player and select next operation, if access file 2 before, access file 1 now, is judged as audio player and selects upper one first operation.File system simulator sends to protocol processing unit the audio player operation information that judges, control wireless host device in play or time-out, a upper head, next etc. mode of operation.
Two, USB Audio pattern if:
As shown in Figure 3, it is identical with USB flash disk pattern that wireless protocols loads flow process, during equipment work, wireless phy interface obtains wireless data, send to protocol processing unit to isolate voice data, voice data formed PCM data after entering audio decoder, and PCM data, by USB Audio passage, send to audio player from USB interface.
If player has the interface of Play Control, can realize Play Control by a HID interface of the many expansions of USB controller.As a good embodiment, as shown in Figure 4, described master controller 22 can also comprise: HID(Human Interface Device, human interface device) interface 2011, this HID interface is connected with described USB controller.By HID interface, can realize a head, next, the basic Play Control such as time-out, broadcasting, fast forwarding and fast rewinding, flow process is that USB controller is resolved the HID order that audio player sends, convert the Play Control order that procotol can be identified to, send to protocol processing unit, by protocol processing unit, Play Control order is sent to wireless host device and realize Play Control.
In traditional ANTENN AUDIO adapter, USB flash disk pattern need to be to voice data the Code And Decode through damaging several times, voice data is had to very large loss, thereby has reduced the signal to noise ratio (S/N ratio) of voice data, affect user's sense of hearing.And in the utility model, for the audio-frequence player device that has USB Audio function, wireless PHY unit simulation is become to a USB Audio main frame, by the mode of sound card, allow player accessing wireless network, the advantage of the mode by sound card is repeatedly coding and decoding, thereby has guaranteed the least disadvantage of wireless data.
As a good embodiment, as shown in Figure 4, described master controller 22 can also comprise: pickup unit 2012, this pickup unit 2012 is connected with described protocol processing unit 222.Pickup unit 2012 gathers local audio data, and after the protocol processes in protocol processing unit, by wireless phy interface, sends to wireless host device, thereby realizes the function of double-directional speech.Concrete, this pickup unit can adopt common on the market microphone to realize.
As a good embodiment, described wireless PHY unit can be wifi radio-cell, blue teeth wireless unit, infrared radio unit, FM(Frequency Modulation, frequency modulation (PFM)) radio-cell or zigbee radio-cell etc.
In addition, the utility model also provides a kind of audio-frequence player device, and it comprises above-mentioned ANTENN AUDIO adapter.
By above scheme, can find out, a kind of ANTENN AUDIO adapter of the present utility model and audio-frequence player device, by reading the mode of usb data, visit the data above wireless network, overcome the limitation of traditional music player with USB interface, the music player that traditional band can be read to USB interface becomes wireless music player, realized the music player of tradition with USB interface and the communication of other wireless device; And the utility model is realized simple, and the hardware cell cost compare adopting is low, has great market using value.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
